Hemerdon Mine case study

  • 15-7-2015

The first metalliferous mine to open in the UK since the 1940s, the Hemerdon Tungsten Mine near Plymouth represents one of the largest new precious metal mining ventures in the UK in more than a generation. In 2013, Blackwell was appointed by Australian miner, Wolf Minerals as Mining Services Contractor on the Hemerdon project - with responsibility for the drilling and blasting of granite ore and waste. In this role, Blackwell will carry out the excavation of nearly 20M cu.m of material over a 6 year period. This will include the excavation of 3 million tonnes per annum of granite ore and 4.5 million tonnes per annum of waste rock, known locally as 'killas'. In addition to mining infrastructure, Blackwell will construct one of the largest and most unique tailings dams in Europe.

The Hemerdon project will see an investment of £15M in a brand new Caterpillar equipment fleet, at the core of which will be three 110t excavators and twelve 65t rigid dump trucks. Equipment will be operated by a locally recruited workforce, as part of the company's drive to provide employment opportunities in an area with a rich surface mining heritage.

Phase One comprises the construction of the Mine Waste Management Facility, encompassing the creation of the tailings dam and associated structures as well as the construction of the primary haul road and site infrastructure. This phase is due for completion in 2015, with Phase Two to commence thereafter. Mining will be undertaken around the clock, with Blackwell's trucks and 50t rehandling loading shovel feeding material into the Client's processing plant on a continuous choke-feed basis. Blackwell's project management team are co-located and fully integrated with the Client team and are currently preparing detailed plans for the Phase Two mining operations.

The award of the Hemerdon project reinforces Blackwell's position as one of the leading operators of heavy mobile equipment in mines and quarries around the UK; sitting alongside load and haul contracts for L'Hoist at Hindlow Quarry and Aggregate Industries at Glensanda and Moorcroft Quarries.
